The utility model is characterized in that a seal locating board is additionally arranged between the cylinder cover and the cylinder cover gasket, and pressure ribs in the cylinder cover cavity are removed; the seal locating board is designed with a window B facing the window A of the spacing board; the middle part of the window B is designed with a pressure rib strip in the perpendicular direction; and the transverse dimension of the window B is smaller than the length dimension of the spacing board. The utility model solves the problem that the locating of the spacing board is not stable and influences the normal opening and closing of the exhaust valve plate in the existing cylinder end assembly, and is beneficial to improving the cylinder cover cavity structure and reducing the noise. The utility model is mainly suitable for improving the cylinder end part in the refrigeration compressor.
Description
(1). technical field: the component that the utility model relates to refrigeration compressor improve especially a kind of high stability noise reduction cylinder head assembly.
(2). background technique: refrigeration compressor sucks refrigerant vapour from vaporizer; Through sucking pipe, enclosure interior space, muffler assembly sqouynd absorption lowering noise; Get into compresser cylinder (suction line) through the suction valve chip suction port; Again through compressor compresses; Gas exhaust piping along exhaust valve plate exhaust port, limiting board, cylinder head, exhaust coil pipe, outlet pipe are formed is discharged compressor and is got into condenser, gets into vaporizer through throttle element throttling step-down, has so constituted the suction and discharge pipeline of whole refrigeration system.In whole suction and discharge pipeline, if limiting board the interference of external factor such as is vibrated and becomes flexible, just normally opening and closing of exhaust valve plate can cause whole refrigeration compressor to run well, and can't realize the refrigerating function of refrigeration compressor.
At present; In order to guarantee that compressor runs well; Generally adopt the beading 2 in traditional cylinder head 1 internal cavities to compress limiting board (referring to Fig. 1) in the refrigeration compressor industry, compress exhaust valve plate, limiting board and exhaust valve plate all can not become flexible because of the interference of external factor such as vibration through limiting board.Thisly utilize the beading on the cylinder head to compress limiting board, realize the location of limiting board, the optimization of the internal structure of cylinder head must be restricted; Can not optimize its internal cavity structures according to the needs of attenuate acoustic noise fully; Can not reduce the refrigeration compressor noise to greatest extent, simultaneously, the beading 2 in traditional cylinder head 1 internal cavities is that the middle part of limiting board is pressed; Does not press at two ends to limiting board; This structure receives interference or the exhaust pressure of external factor such as bigger vibration when big at refrigeration compressor, because impacting force is inhomogeneous, becoming flexible may appear in exhaust valve plate; Cause the normally opening and closing of refrigeration compressor exhaust valve plate, refrigeration compressor can't be realized its refrigerating function.In addition, the traditional air cylinder edge is the plane, and through cylinder head plane clamping cylinder lid pad, owing to there is not protruding sealed muscle on the cylinder head plane, this cylinder head may reduce the refrigerating capacity and the COP of compression because of sealing the bad leakage that produces.
The (3) summary of the invention: the purpose of the utility model is exactly that limiting board, the exhaust valve plate that will overcome in traditional refrigeration compressor cylinder head assembly are located built on the sand; Work long hours and receive to occur becoming flexible after the vibration interference; Influence the proper functioning of exhaust valve plate; Need the design beading to compress limiting board in the tradition cylinder head cavity, be unfavorable for problems such as noise reduction, a kind of high stability noise reduction cylinder head assembly is provided.
The concrete scheme of the utility model is: the cylinder head assembly to existing refrigeration compressor improves; It includes cylinder head, cylinder head gasket, valve plate, suction valve chip, the valve plate pad of butt joint successively; Relief opening over against valve plate is furnished with exhaust valve plate and limiting board; On cylinder head gasket, be designed with window A, it is characterized in that: between cylinder head and cylinder head gasket, have additional a sealing positioning plate, save the beading in the cylinder head cavity simultaneously over against limiting board; Window A over against limiting board on the said sealing positioning plate is designed with window B, is designed with the beading bar of vertically arranging at the middle part of window B, and the transverse dimension of window B is less than the length dimension of limiting board.
The positioning plate of sealing described in the utility model thickness is 1-4mm.
The positioning plate of sealing described in the utility model is to adopt steel plate or aluminium alloy plate or alloy sheets to process.
In order to improve sealing effect, the positioning plate of sealing described in the utility model leans on the one side of cylinder head gasket to be designed with a circle sealed muscle along periphery, and the width of sealed muscle is 0.5-1.5mm, high 0.10-1.25mm.
In order to cooperate the structure shape of limiting board, that more fits compresses, and the beading bar on the said sealing positioning plate of the utility model protrudes to cylinder head one side bending.
For increasing noise reduction, said sealing positioning plate has auxiliary hole on the right side described in the utility model, and to increase the cavity volume of cylinder head, four jiaos of the sealing positioning plate have four bolts hole, is connected with the cylinder head assembling with convenient.Certainly the sealing positioning plate can also be an one with cylinder head welding dress, then need not to offer bolt hole.
The utility model is owing to set up the sealing positioning plate; The sealing positioning plate is through the beading bar in the middle of the both sides portion of window and the window limiting board and exhaust valve plate to have been carried out at 3 to compress the location; Therefore it is very firm to compress the location; Can not occur becoming flexible, guarantee that the exhaust valve plate long-term work is normal, the beading in the cylinder head is able to cancellation simultaneously; Make the inner cavity of cylinder head carry out optimal design to greatest extent, thereby reduce the noise of whole refrigeration compressor according to the needs that reduce pneumatic noise.Design sealed muscle on the sealing positioning plate in the utility model in addition, can strengthen the sealing effect of cylinder head assembly.
